Selecting, storing & prepping soy milk
- Selecting
- Soy milk stands out among plant-based milks for having a protein content close to dairy milk, since soybeans are naturally protein-rich; checking for added sugar is worthwhile as many flavored versions add significant amounts.
- Storing
- Shelf-stable (aseptic carton) soy milk keeps unopened at room temperature until the printed date; once opened, or if refrigerated from purchase, use within 7-10 days.
- Prepping
- Shaking or stirring soy milk before pouring redistributes any natural separation of solids that settles during storage.
Storage guidance from the USDA FoodKeeper database (FSIS, Cornell University, and the Food Marketing Institute).

Key metrics
Nutrient density
Per 100 kcal, soy milk delivers about 13% of a Daily Value on average across 22 beneficial nutrients. The score is its percentile for that measure among the 177 foods in our database — higher means more nutrition per calorie. How this is calculated.
- More vitamin A than 84% of foods · 100% of beverages
- More calcium than 82% of foods · 78% of beverages
Density counts protein, fiber, and vitamins and minerals (not fat, sodium, or sugar), each capped so a single nutrient can’t dominate, with a calorie floor so very-low-calorie foods aren’t overstated. It measures nutrition per calorie within our database — a useful guide, not a complete verdict on how “healthy” a food is.
